Description

一种通信网络系统、 寻找家庭基站策略网元的方法及装置
技术领域
本发明涉及通信技术领域, 具体涉及一种通信网络系统以及寻找家庭基 站策略网元的方法和装置。
背景技术
第三代合作伙伴计划 ( 3rd Generation Partnership Project, 简称为 3GPP ) 演进的分组系统( Evolved Packet System, 简称为 EPS )由演进的通用移动通 信系统陆地无线接入网 ( Evolved Universal Terrestrial Radio Access Network , 简称为 E-UTRAN ) 、 移动管理单元(Mobility Management Entity, 简称为 MME )、 服务网关( Serving Gateway, S-GW )、 分组数据网络网关(Packet Data Network Gateway,简称为 P-GW或者 PDN GW)、归属用户服务器( Home Subscriber Server, 简称为 HSS ) 、 3 GPP的认证授权计费 (Authentication, Authorization and Accounting , 简称为 AAA )服务器, 策略和计费规则功能 ( Policy and Charging Rules Function, 简称为 PCRF )实体及其他支撑节点组 成。
图 1是根据相关技术的 EPS的系统架构的示意图。 如图 1所示, 移动性 管理实体负责移动性管理、 非接入层信令的处理和用户移动管理上下文的管 理等控制面的相关工作; S-GW是与 E-UTRAN相连的接入网关设备, 在 E-UTRAN和 P-GW之间转发数据,并且负责对寻呼等待数据进行緩存; P-GW 则是 EPS与分组数据网络( Packet Data Network, 简称为 PDN ) 网络的边界 网关,负责 PDN的接入及在 EPS与 PDN间转发数据等功能; S-GW和 P-GW 都属于核心网网关; PCRF是策略和计费规则功能实体, 它通过接收接口 Rx 和运营商网络协议( Internet Protocol , 简称为 IP )业务网络相连, 获取业务 信息, 此外, 它通过 Gx/Gxa/Gxc接口与网络中的网关设备相连, 负责发起 IP承载的建立,保证业务数据的服务质量(Quality of Service, 简称为 QoS ) , 并进行计费控制。
EPS 支持与非 3GPP 系统的互通, 其中, 与非 3GPP 系统的互通通过 S2a/b/c接口实现, P-GW作为 3GPP与非 3GPP系统间的锚点。 在 EPS的系 统架构图中,非 3GPP系统被分为可信任非 3GPP IP接入和不可信任非 3GPP IP接入。 可信任非 3GPP IP接入可直接通过 S2a接口与 P-GW连接; 不可信 任非 3GPP IP接入需经过演进的分组数据网关( Evolved Packet Data Gateway, 简称为 ePDG )与 P-GW相连, ePDG与 P-GW间的接口为 S2b, S2c提供了 用户设备 ( User Equipment, 简称为 UE )与 P-GW之间的用户面相关的控制 和移动性支持, 其支持的移动性管理协议为支持双栈的移动 IPv6 ( Moblie IPv6 Support for Dual Stack Hosts and Routers, 简称为 DSMIPv6)。
在 EPS系统之中,策略和计费执行功能( Policy and Charging Enforcement Function, 简称为 PCEF ) 实体存在于 P-GW中, PCRF与 P-GW之间 Gx接 口 (见图 1 )交换信息。 当 P-GW与 S-GW间的接口基于 PMIPv6时, S-GW 也具有承载绑定和事件报告功能 ( Bearer Binding and Event Report Function, 简称为 BBERF )实体对业务数据流进行 QoS控制, S-GW与 PCRF之间通过 Gxc接口 (见图 1 )交换信息。 当通过可信任非 3GPP接入系统接入时, 可信 任非 3GPP接入网关中也驻留 BBERF。 可信任非 3GPP接入网关与 PCRF之 间通过 Gxa接口(见图 1 )交换信息。当 UE漫游时, S9接口作为归属地 PCRF 和拜访地 PCRF 的接口, 同时为 UE 提供业务的应用功能 (Application Function, 简称为 AF ) , 通过 Rx接口向 PCRF发送用于制定策略和计费控 制 (Policy and Charging Control, 简称为 PCC )策略的业务信息。 在 3 GPP 中,通过接入点名称( Access Point Name ,简称为 ΑΡΝ )可以找到对应的 PDN 网络。 通常将 UE 到 PDN 网络的一个连接称为一个 IP 连接接入网 (IP Connectivity Access Network, 简称为 IP-CAN )会话。 在建立 IP-CAN会话的 过程中, BBERF和 PCEF分别与 PCRF之间建立 Diameter会话, 通过这些 Diameter会话来传送对这个 IP-CAN会话进行控制的策略计费信息和用于制 定策略的信息等。
与之对应的 BBF ( Broadband Forum 宽带论坛)提出了宽带策略控制架 构 BPCF ( Centralized Deployment Functional Architecture 集中式部署功能架 构),如图 2所示, BPCF主要功能是制定相应的策略; PEF( Policy Enforcement Point 策略执行点)通常驻留在固网传输设备中, 例如: BRAS ( Broadband Remote Access Server 覔带接入月良务器 )/BNG( Broadband Network Gateway ), 根据 BPCF制定的相应策略进行执行; AAA( Authentication, Authorization and Accounting认证, 授权计费服务器) , 储存用户签约信息。 AF ( Application Function 业务应用功能) , 为 BPCF制定策略, 提供相应的业务信息。 固网 中实现策略控制, 相比移动网络的区别在于, 固网策略决策实体除了基于业 务和签约制定策略, 还需要做资源接纳控制, 根据 UE的接入位置, 判断 UE 的数据流的流经路径, 从而基于对该路径上的资源做出判断, 是否接纳该业 务。
现在运营商很关注的 FMC ( Fixed Mobile Convergence固网移动融合) 场景, 就^^于对 3GPP和 BBF互联互通进行研究。 如图 3所示, 给出了 UE通过固网 BBF接入 EPS核心网示意图。 对于用户通过 BBF固网接入移 动核心网的场景, 是需要对整个数据的路由路径 (数据会经过固网和移动网 传输)上的 QoS进行保证的。 当移动用户 UE通过 BBF固网接入时, PCRF 不仅需要基于业务和签约制定策略, 还需要通过 S9* ( PCRF和 BPCF之间 ) 接口向 BPCF发起接纳控制请求(请求消息中可能含有用户位置, 标识之类 的信息用于告知 BPCF用户的接入位置 ) , 现有的 PBCF做接纳控制的步骤 如下所示, 包括:
第一步, 识别 UE的接入位置;
第二步,判断 UE数据流的流经路径,例如: RG ( Residential Gateway 家 庭网关) , AN ( Access Note 例 ¾口: DSLAM Digital Subscriber Line Access Multiplexer数字用户线接入复用设备) , BRAS ( Broadband Remote Access Server 宽带接入服务器) /BNG ( Broadband Network Gateway )等设备。
第三步, 判断路径上各个节点的资源情况, 如果节点上资源能满足该数 据流的要求, 允许接纳 BPCF完成接纳控制决策后, 向 PCRF返回结果。 因 此, BPCF做接纳控制依赖用户 UE的接入相关信息, PCRF可以通过 S9*告 知 BPCF。
如图 4所示,给出了 UE通过 3GPP Femto方式接入 EPS核心网示意图。 针对 UE通过 H(e)NB (家庭基站 )接入( 3GPP Femto方式接入 ) 的场景, 当 H(e)NB上电时, H(e)NB会获得由固网 BBF分配的 IP地址, 由于实际运 营网络的部署有差异, IP地址的分配方式存在以下 2种(区别在于部署家庭 网关 RG的功能方式不同: 桥接方式和路由方式) :
第一种, 路由方式
如图 5所示, UE通过 H(e)NB接入 RG,通过 AN汇聚后接入 BRAS/BNG, 此时的 RG作为路由方式, UE的 IP地址是由 RG分配的(例如: H(e)NB接 入 RG, 釆用用户名密码的方式在 RG上认证, 认证成功 RG为 H(e)NB分配 内部地址 ) , 而 RG的 IP地址由 BRAS/BNG分配(例如: 在 RG上电时, RG向 BRAS/BNG发起认证, BRAS/BNG为该 RG分配地址 ) , 此时 RG需 要做 IP地址转换, 将 H(e)NB 的私网地址转换成公网地址 CPE ( Customer Premise Equipment -- 用户驻地设备 / 用户端设备) 地址, 该地址可以是 BRAS/BNG为 RG分配的地址。
第二种, 桥接方式
如图 6所示, UE通过 H(e)NB接入(网络部署中可能存在 RG, 如果存 在, 此时的 RG具有桥接功能, RG只是一个二层设备, 不为用户分配 IP地 址, 和 H(e)NB及 BRAS/BNG之间的连接是二层的连接) , 再通过 AN接入 BRAS/BNG, 该 H(e)NB的 IP地址是由 BRAS/BNG分配的。
现有技术提出, 可以针对 3GPP Femto接入, 设定一个新的网元 H(e)NB PF ( Policy Function, 策略功能) , 如图 7所示, 用于该场景下的接纳控制; 安全网关 Sec-GW和家庭基站 H(e)NB之间会建立 IP-sec隧道(IP-Sec安全 隧道保证数据传输过程中的加密安全) , 该隧道的隧道信息 (包括: 隧道外 部的 IP地址和 /或端口 )。如果家庭网关 RG是路由方式,由于此时的 H(e)NB 的 IP地址可能是 RG分配的内网地址, Sec-GW需要向 Η(»ΝΒ PF传递 CPE IP地址和 H(e)NB IP地址(该 CPE IP地址是隧道的外部 IP地址, 而 H(e)NB IP地址是内部 IP地址 );如果家庭网关 RG是桥接方式, H(e)NB的地址是由 BRAS/BNG分配的地址 , Sec-GW向 H(e)NB PF传递 H(e)NB的 IP地址信息 , 可以不用传递 CPE IP地址(此时 CPE的 IP地址可能和 H(e)NB的 IP地址一 致) 。
如图 8所示, 相应的 H(e)NB GW/MME需要将 QoS信息(例如: 带宽 ) 和 H(e)NB的 IP地址传递给该 H(e)NB PF (实际网络部署中可能不存在 H(e)NB GW,此时 MME传递 QoS信息)。 当然除了上述 H(e)NB GW/MME传递 QoS 信息之外, 如图 9所示, 还有另一种方式: 由 H(e)NB自己上报 QoS信息和 H(e)NB的 IP地址。由此 H(e)NB PF将获得的隧道信息和 QoS信息送给 BPCF, BPCF就可以根据隧道信息判断 H(e)NB的位置, 再根据 QoS信息对请求的 资源做接纳控制。
现有技术中, 对于网络中有多个策略和计费规则功能实体 PCRF的选择 由网元 DRA ( Diameter Routing Agent, Diameter路由实体)来实现, DRA 是保证同一个 IP-CAN会话或一个 UE的多个会话由同一个 PCRF来处理(例 如: 根据 APN信息) ; 而当网络中存在多个 H(e)NB PF时, 同一个 H(e)NB 下的所有会话需要由一个 H(e)NB PF来处理, 如何保证为一个 H(e)NB服务 的 Sec-GW和 H(e)NB GW/MME/H(e)NB找到同一个 H(e)NB PF, 是本发明 需要解决的问题。 发明内容

如图 10a所示, Sec-GW发送给 H(e)NB PF SF的消息中携带 CPE IP地 址和 H(e)NB IP地址和 /或标识; H(e)NB GW/MME (若网络中不存在 H(e)NB GW, 则由 MME发送消息)发送给 H(e)NB PF SF的消息中携带 H(e)NB IP 地址和 /或标识。 H(e)NB PF selection Function根据 H(e)NB IP地址或标识选 择 H(e)NB PF, 并保存该关联关系。 若本地保存的信息中已有该关联关系, 则直接选择即可。
如图 10b所示, Sec-GW发送给 H(e)NB PF SF的消息中携带 CPE IP地 址和 H(e)NB IP地址和 /或标识; H(e)NB发送给 H(e)NB PF SF的消息中携带 H(e)NB IP地址和 /或标识。 H(e)NB PF selection Function根据 H(e)NB IP地址 或标识选择 H(e)NB PF, 并保存该关联关系。 若本地保存的信息中已有该关 联关系, 则直接选择即可。 在上述两种架构中, 所述家庭基站策略功能选择模块, 接收为家庭基站 选择家庭基站策略功能实体的请求消息, 在第一次收到请求消息时, 根据选 择策略为该家庭基站从一个或多个家庭基站策略功能实体中选择一个家庭基 站策略功能实体, 并保存该家庭基站与所选择的家庭基站策略功能实体的关 联关系; 若后续再收到其他的为同一家庭基站选择家庭基站策略功能实体的 请求消息时, 则根据所保存的关联关系直接选择与该家庭基站关联的家庭基 站策略功能实体。
该关联关系是家庭基站与家庭基站策略功能实体之间的对应关系, 即家 庭基站的 IP地址或标识与家庭基站策略功能实体的地址之间的对应关系。
该逻辑功能模块 H(e)NB PF selection Function 可以单独部署或和
DRA/H(e)NB PF ^―,如果与 DRA合设,则 DRA需要增强相应的功能来实 现。
下面结合附图和具体实施例对本发明所述技术方案作进一步的详细描 述。
实施例一:该实施例针对图 10a所示的架构, H(e)NB PF selection function 釆用重定向方式。
由于目前实际网络中, H(e)NB GW的部署还处于可选, 所以当网络中不 存在 H(e)NB GW时, 可由 MME和 H(e)NB PF交互。 如图 11所示, 显示了 针对图 10a所示系统架构的釆用重定向方式时的流程图, 包括:
步骤 1101、 H(e)NB上电, H(e)NB向 Sec-GW建立 IP-Sec隧道。
步骤 1102、 Sec-GW需要向 H(e)NB PF发送消息, Sec-GW先将消息发 送给 H(e)NB PF selection function, 所述消息中包含: 隧道信息, CPE IP地 址(该 IP地址是固网为 CPE设备分配的 IP地址 ) , H(e)NB的 IP地址和 / 或 H(e)NB的标识 , 所述 H(e)NB IP地址是移动网络为 H(e)NB分配的。
步骤 1103、 H(e)NB PF selection function可以查询本地保存的信息,如果 有该 H(e)NB的关联信息, H(e)NB PF selection function向 Sec-GW返回该 H(e)NB关联的 H(e)NB PF的地址信息; 如果没有该 H(e)NB的关联信息, H(e)NB PF selection function就选择一个 H(e)NB PF为该 H(e)NB服务, 保存 该关联关系 (该关联关系是选择的 Η(»ΝΒ PF的地址和该 Η(»ΝΒ的关联关 系) , 并返回给 Sec-GW该 H(e)NB PF的地址信息。
若 H(e)NB PF selection function没有该 H(e)NB的关联信息, H(e)NB PF selection function第一次为该 H(e)NB选择 H(e)NB PF时, 可以按照依照运营 商配置或基于当前负载情况进行选择, 若已保存有关联信息, 则可以直接根 据该关联关系进行选择,例如通过该 Η(»ΝΒ的 IP地址查找对应的关联关系, 进而找到关联的 H(e)NB PF。
步骤 1104、 Sec-GW收到消息后向该 H(e)NB PF发送消息。
步骤 1105、 H(e)NB PF返回响应。
步骤 1106、 当 H(e)NB GW/MME受到触发需要向 H(e)NB PF发送消息 时, 例如: UE通过 H(e)NB接入附着到网络上, 发起附着流程, 或是会话过 程中发生承载修改。 由于目前实际网络中, H(e)NB GW的部署还处于可选, 所以当网络中若不存在 H(e)NB GW时 , 则由 MME和 H(e)NB PF交互。
步骤 1107、 H(e)NB GW/MME需要向 H(e)NB PF发送消息时, H(e)NB
GW/MME先向 H(e)NB PF selection function发送消息, 所发送的消息中携带 H(e)NB的 IP地址和 /或 H(e)NB的标识 , 所述 H(e)NB IP地址是移动网络为 H(e)NB分配的。
步骤 1108、 H(e)NB PF selection function查询本地保存的信息 (可以是选 择的 H(e)NB PF的地址和该 H(e)NB的关联关系),向 H(e)NB GW/MME返回 该 H(e)NB关联的 H(e)NB PF的地址信息;

实施例二 该实施例针对图 10a所示的架构, H(e)NB PF selection function 釆用中继方式。
由于目前实际网络中, H(e)NB GW的部署还处于可选, 所以当网络中不 存在 H(e)NB GW时, MME和 H(e)NB PF交互。 如图 12所示, 在中继方式 下的流程包括:
步骤 1201、 H(e)NB上电, H(e)NB向 Sec-GW建立 IP-Sec隧道。
步骤 1202、 Sec-GW需要向 H(e)NB PF发送消息时, Sec-GW将消息发 送给 H(e)NB PF selection function, 所述消息中包括: 隧道信息, H(e)NB的 IP地址和 /或 H(e)NB的标识 , 所述 H(e)NB IP地址是移动网络为 H(e)NB分 配的, 其中隧道信息是指隧道头的外部 IP地址: CPE IP地址。
步骤 1203、 H(e)NB PF selection function查询本地保存的信息(保存的信 息可以是 H(e)NB PF的地址和该 H(e)NB的关联关系 ) , 如果有该 H(e)NB 的关联信息, H(e)NB PF selection function向该 H(e)NB关联的 H(e)NB PF转 发该消息; 如果没有该 H(e)NB的关联信息, H(e)NB PF selection function就 选择一个 H(e)NB PF为该 H(e)NB服务, 保存该关联关系 (该关联关系可以 是选择的 H(e)NB PF的地址和该 H(e)NB的关联关系 ) , 并向该 H(e)NB PF 转发所述消息。
若 H(e)NB PF selection function没有该 H(e)NB的关联信息, H(e)NB PF selection function第一次为该 H(e)NB选择 H(e)NB PF时, 可以按照依照运营 商配置或基于当前负载情况进行选择, 若已保存有关联信息, 则可以直接根 据该关联关系进行选择,例如通过该 Η(»ΝΒ的 IP地址查找对应的关联关系, 进而找到关联的 H(e)NB PF。
步骤 1204、 H(e)NB PF返回响应。
步骤 1205、 H(e)NB PF selection function转发响应消息给 Sec-GW。
步骤 1206、 当 H(e)NB GW/MME受到触发需要向 H(e)NB PF发送消息 时, 例如: UE通过 H(e)NB接入附着到网络上, 发起附着流程, 或是会话过 程中发生承载修改。 由于目前实际网络中, H(e)NB GW的部署还处于可选, 所以当网络中不存在 H(e)NB GW时, 由 MME和 H(e)NB PF交互。
步骤 1207、 H(e)NB GW/MME需要向 H(e)NB PF发送消息时, H(e)NB GW/MME 先向 H(e)NB PF selection function发送消息, 所述消息中携带 H(e)NB的 IP地址和 /或 H(e)NB的标识, 所述 H(e)NB IP地址是移动网络为 H(e)NB分配的。
步骤 1208、 H(e)NB PF selection function查询本地保存的信息(保存的信 息可以是 H(e)NB PF的地址和该 H(e)NB的关联关系) , 向该 H(e)NB关联 的 H(e)NB PF转发该消息;
步骤 1209、 H(e)NB PF向 H(e)NB PF selection function返回响应。
步骤 1210、 H(e)NB PF selection function向 H(e)NB GW/MME转发响应 消息。
除了上述实施例 1和 2中的重定向方式和中继方式, 还存在一种混合方 式, 在 Sec-GW, H(e)NB GW/MME第一次需要和 H(e)NB PF交互时, 先釆 用中继的方式和 H(e)NB PF selection function交互,从返回的响应消息中获取 H(e)NB PF的地址信息,安全网关 Sec-GW, H(e)NB GW/MME保存该 H(e)NB PF 的地址信息, 后续直接和 H(e)NB PF 交互, 就不用再通过 H(e)NB PF selection function转发消息。
